Overlapping semi-persistent scheduling for multiple transmit receive points

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message for a semi-persistent scheduling (SPS) configuration that corresponds to an SPS configuration index. The UE may determine a control resource set (CORESET) pool index value from the message and associate a CORESET pool index value of an SPS physical downlink shared channel with the CORESET pool index value of the message. Numerous other aspects are provided.
